Camshaft Theory by Elgin
Created: January 28, 2006
Considerable information has been recorded about numerous aspects of the four stroke internal combustion engine. Nevertheless, only a small percentage of people really understand how it works and even fewer still know how to modify an engine to suit their needs. I will try to simplify this complex subject by discussing some basic principles that may be overlooked or misunderstood by the average person. First, it is very important to understand the relationship between piston travel directions and valve timing events. The reason this relationship is important is because it is one of the few things that is relatively easy to adjust/change. The camshaft which opens and closes the valves makes ONE complete revolution (360 degrees) while the crankshaft moving the piston up and down the cylinder rotates TWICE (720 degrees). Camshaft timing is usually expressed in terms of crankshaft degrees relative to the piston location in the cylinder. That is, relative to Top Dead Center (TDC) and Bottom Dead Center (BDC), respectively. Note that during the four strokes of a piston in an internal combustion engine the crankshaft will rotate 720 degrees and the piston will be at each TDC and BDC twice.
Kent Camshaft Fitting Rules
Created: January 27, 2006
The installation and first few moments of running are critical factors in the life of the camshaft and the following instructions have been devised in order to obtain maximum performance from the engine and to ensure a long and trouble free life from both the camshaft and associated components. These points are designed to be used in conjunction with the original manufacturers installation procedure.

Created: January 27, 2006
Established in the late 1970’s, Kent Performance Cams has grown from a fledgling idea nurtured by two engineers - Bob Munt and Bob Fry - into a world renowned specialist camshaft manufacturing team, a camshaft manufacturing house that was capable of producing competition engine components within strict quality control criteria whilst still remaining cost effective, a policy we still pursue to this day.Bob Fry - who took full control of the company in 1989 - has since taken a back seat in the running of the company leaving the existing management team - Tony Woodward, Andy Burns, Malcolm Hawkins and Graham Watts - as the primary Directors responsible for further growth of the company. Other key employees include Sales Manager Del Johnson, whose automotive experience spans thirty years.
Kent Camshaft Timing

Classic Mini Clutch Design and Technical description
Created: February 16, 2000
One of the more common questions asked by Mini owners is "why doesn't my clutch disengage properly?" or "why is it hard to engage gears?" The usual symptom is that the clutch engages right at the floor and you find yourself embedding the pedal in the carpet to avoid grinding gears. Given that the clutch worked properly when the car left the factory the obvious answer is 'wear'.

The new generation of short period, high lift cams have been developed to give the best results in large bore engines when used in conjunction with 1.5 ratio, hi-lift rockers. For the small bore range, the stock 1.3 ratio is optimum. In certain instances ratios of 1.7 to 1 are of benefit - but is really only applicable to fully developed race engines.

A selected range of modified cylinder heads are available to suit a wide variety of applications. All port and chamber modifications are carried out by experts to current state of the art specifications. Therefore, actual specifications may alter slightly as gas flow and port velocity efficiency improvements are developed. Where large bore heads are used on small bore engines (i.e. 12G940 casting on 948/1098cc block), it is necessary to check full lift of exhaust valve, and pocket the block as necessary.

Cylinder Heads
Created: January 30, 2000
Everybody has their own opinion on this subject. The most experienced people will tell you that the best way to maintain your engine performance is to accept the fact that valve jobs need to be done 2 or 3 times more often than rings and bearings! And this data base was concluded when leaded gas was the norm! Now that unleaded is all you can get, valve jobs are needed even more often! The purpose of a valve job is two fold; first the valve seats. The impurities in the air and gas often get trapped between the valve and the seat in the head; under worst conditions stopping the valve from closing, but more commonly being smashed enough to allow just a little seepage of hot gases.

On the 1275 Mini there is something to look out for that doesn't arise on an inline engine. Due to the proximity of the gear box webs at both ends, there is not enough clearance for the nut.

Carburetors: Conversion from Injection to Carburetors
Created: April 15, 2005
In the history of the Mini the drive to keep the product alive and marketable meant the factory decided to modernize the fuel system of the Mini from Carb to Fuel Injection. Thus in 1991 the first FI was installed on the Mini. Know as Single Point Injected or SPI for short, the system also incorporated its first ECU into the car. This version of the Mini was produced until late ’97 when it was changed to the Twin Point injected version (also know as a MPI Mini.
A Basic Guide to Electronic Fuel Injection for Minis
Created: February 16, 2000
If done properly, converting your Mini to EFI can have many benefits. The EFI Engine Control Unit (ECU) can control all aspects of the combustion of the air/fuel ratio under all conditions. For each and every load point throughout the rev range that the engine may experience, the EFI ECU can calculate the optimum timing and delivery of fuel as well as precisely when ignition will take place by supplying spark at exactly the right time in order to maximise power and torque.

One of the common problems where sidedraft carbs are involved is the choice of carb size in the first place and choke size in the second. The trick with carb sizing and choke selection is basically one of choosing a size which provides the engine with the airflow it needs without going over the top.

Synchronization of Twin SU HS-type Carburetors
Created: January 29, 2000
Before proceeding to synchronize your carburetors and for best results, some preparation is in order. Your carburetors should be in peak condition with no play in the throttle shaft bushings. If these bushings are worn, synchronization is difficult or impossible to achieve since there will be a vacuum leak past the bushings. Additionally, the jet needles should be identical and correct for the application; adjusted to equal and correct seating in the piston and centered in their jet bores (if not centered, you will feel a bind when moving the piston up and down).

Quaife Limited Slip Differentials - Classic Mini Cooper
Created: January 26, 2006
The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

The standard drop gears are fine for practically all road use - almost irrespective of power output. Despite what many folk believe - they are more than strong enough, and will perform perfectly well if correctly set up.

‘Salisbury’ is the word banded about by most un-enlightened folk when discussing LSDs for Minis, mistakenly believing the word covers all Mini orientated LSDs. This is grossly incorrect. The ‘Salisbury’ was designed in the ‘50s at a time when racecars were a good deal less sophisticated than today. Tyres were usually cross-ply with severely limited grip due to poor compounds developed ostensibly for rear-wheel-drive cars; the front wheel drive of the Mini being a rarity.

As a Mini Cooper will naturally understeer in order to get closer to a balance, we either have to decrease the understeer OR INCREASE oversteer.

Mini suspension, steering and handling data
Created: June 08, 2000
The data on this page relates to all Minis unless specified. Major changes to suspension and steering are limited to the introduction of a new steering rack and steering arms for Mk2-on models. Mk2 steering arms have two `ears' to aid in the use of ball joint splitters; this is how they may be differentiated from Mk1 steering arms.

Sway Bar Information and Theory
Created: January 30, 2000
A car has "neutral" steering when while turning in tight circle at moderate speed the car will complete the circle at approximately the same position across the diameter of the circle. A car has "understeer" when turning on the same tight circle at the same moderate speed the diameter of the circle is increased because of the front wheels "pushing" out!
Mini coil over conversion kit, CK17
Created: January 29, 2000
This kit has been designed specifically for road use with the view to limited tarmac competition events. If used for “off-road” purposes, strengthening modifications will need to be made, as failure may be a possibility. All wheels and tire combinations fitted to the vehicle should be inspected as it is essential that there is enough clearance between the wheel . tire and suspension units. Very minor adjustments using wheel spacers may be required otherwise.
Fixed negative camber bottom arms, C-AJJ3364
Created: January 29, 2000
These are a direct replacement for the standard bottom arms and will add 1½° of negative camber to whatever the car has as standard - quoted by the manufacturers as being 1° positive, + 1°. If the car has 1° positive, fitting the negative camber arms will give ½° camber. Measuring what the car has with standard arms will help determine what camber setting will be achieved by using C-AJJ3364. Negative camber helps reduce under steer, therefore improving the cars cornering performance.
Front bump stop kit, C-AJJ4007
Created: January 29, 2000
Remove existing bump rubber completely. The smaller hole of the new bump rubber should be fitted over the retainer on the bracket, using hand soap or brake fluid on the rubber if necessary to ease the fitting.

Heavy duty adjustable tie-rods
Created: January 29, 2000
These rods have been produced to improve car stability when cornering and braking, and facilitate easy adjustment of castor angle. Manufactured from a high grade material in a much bigger diameter, they are less susceptible to bending than the standard items. The standard castor angle is 3° + ½°. This will change when the car is raised or lowered, and when adjustable or negative camber bottom arms are used (these tend to increase castor).
